Comment (by adamsilverstein):

 [attachment:"37134.6.diff"] adds some unit tests that verify the filter
 works correctly.

 I included the test cases @joehoyle added in #24157
 (https://core.trac.wordpress.org/attachment/ticket/24157/kses.diff) and
 verified both that these are cleared currently and that the filter can be
 used to enable these cases.

 Adding a filter unblocks these specific use cases without changing the
 current behavior.

 @azaozz does this look ok to you, or do you think we should go further and
 change the regex itself?
